Great choice of mage helpers for Anders' exorcism. I think only people who felt some obligation towards him would be willing to perform this onerous task at the present time.

I also felt the tidbit that Elissa and the Wardens were helping to keep Anders and his clinic relatively safe was a great addition. It makes perfect sense.

The issue of Anders potentially becoming Tranquil from this ritual is sad and very believable. I like that it is more risky than freeing Connor, because that seems very logical.

I also sadistically enjoy the fact that it will take some blood magic to help fix Anders up. I always felt his adamant refusal of blood magic was hypocritcal after he chooses to be possessed by a spirit.
